Boyz II Men's Wanya Morris is under scrutiny for his reported strained relationships with his older children, drawing comparisons to Brian McKnight.

The singer is set to perform at the MotorCity Casino Hotel in Detroit, Michigan, on June 9. Brian McKnight fans are planning to boycott his upcoming concert after he called his estranged children, including his cancer-stricken son Niko, "evil" and the "product of sin.

The singer claimed he tried to offer his son Niko help but was forced by his ex-wife to stop aiding and contacting him.

"In order to live a life that you love, you have to get rid of the evil and the negativity, even if that evil and negativity is related," he said on Instagram.
